Machining indexable cutting insert M40 PVST

millingcarbidefor stainless steel

BRIGHT PROSPECTS... M40 and PVST are features for efficient machining of stainless-, acid- and heat-resistant materials. Extremely tough and high-temperatureresistant carbide in combination with our modified AlTiNcoating layer reduce built-up edges, increase thermal stability and reduce friction between cutting edge and material at the same time. This results in a maximum process reliability, even with highest possible chip volume and results in lower costs per component. TECHNICAL INFORMATION Due to the reduced arc of contact, when machining vertical moulds, less cutting forces influence milling cutters, inserts and machine spindle. These following graphics explain the kind of geometry influence to those cutting forces. One further element is the reduced power consumption of the machine, which allows more careful treatment of the machine Comparing different arcs of contact for increasing cutting depths (ap up to ap 3) illustrate the reason of better running smoothness. As soon as the ap-value has exceeded the size of our QUADWORX®-insert’s minor cutting edge (ap 3), the milling cutter gets a side clearance and thus it is cutting free and radial forces for milling cutter, inserts and machine spindle are decisively reduced.
